computer freezes, lag when typing, etc help please
Recently my computer has been experiencing a good amount freezes, especially when my computer screensaver kicks in, as well as a large amount of lag when typing documents. Also my usb drives do not pick up hardware; such as a mouse or printer usb chords unless i reboot the computer with it already plugged in. I did aquire a virus called a HTML_IFRAME.HT but did infact have it deleted. yet I have done countless virus scans, adware scans and spyware scans but have not found anything and the problem still persists.
I also defragged my computer. So i am pretty much stumped as to what i can do to fix this. My laptops battery does need changing so is it possible that a dead battery could be causing these slowdowns? and if not what can i do to fix this
any help will be appreciated
